Ok, so let's take this one at a time.
-snip-
Feminists: If Trump and the GOP are in power, they can be used as boogeymen, leading to greater amounts of feminist activist activity. Under Obama, they were a bit too focused on all these other non-politician boogeymen, which often ended up backfiring for them. Also, the Democratic Party is proven to be weak and inefficient at actually enacting policies anyway, so why not vote GOP in the meantime until they buff themselves up?
Environmentalists: Honestly I'm not too sure lol. Maybe the same kind of argument as for feminists?
Animal Rights Activists: Ditto
People with large amounts of student debt: Better economy, a party that encourages personal responsibility --> people actually being able to pay their loans one bite at a time, rather than impotently wait for some savior (ala Bernie Sanders) that may never come.
Smh I expected better on the last few sections...
Feminists: most 3rd-wave feminists aren't that Machiavellian... I can see why they could secretly vote for Trump in 2016 but not in general or consistently. The only quasi-legit argument I can think of is the Islamophobe one, i.e. "radical Islam is an existential threat to gender equality and sexual liberation as it exists in the Anglophone West. If the status quo continues our safety and liberty will be at risk".
Environmentalists: I agree with Skill and Chance's prediction that a more protectionist GOP will have more environmentalist support, because both groups oppose neoliberal economic policies.
Also, people generally don't vote against the Dems on environmental issues; it has more to do with educational attainment, the urban-rural divide, and the ongoing culture wars, which are manifested in the debate around immigration and PC culture. All this means GOP voters who care about the environment won't be persuaded to vote Dem just because the GOP is anti-science and tolerates climate change denial. We need both major parties competing to find and deliver solutions to CO2 emissions reductions, renewable energy development, and infrastructure overhaul. This can't happen until a critical mass of environmentalist (donors) start supporting the Republican party.
Animal rights activists: the global economy's reliance on transport is detrimental to animal well-being, encourages unethical animal experimentation, leads to the treatment of livestock as commodities, etc. Not too sure on this one either
Student debt: 4-year college is a scam, the Dems are running a pyramid scheme to screw you all over, they're trying to brainwash you into SJWs, etc. This doesn’t help people who already have a lot of student loan debt though
Overall, not a bad job. Your argument that Asians should support the GOP purely due to affirmative action doesn't hold for Asian Americans who aren't NYC working-class Chinese, because the situation with NYC public schools is unique to that community.
